CFPO : Counterfactual Policy Optimization For Multimodal Reasoning

ICML 2026poster

Large Vision-Language Models (LVLMs) have demonstrated remarkable capabilities in multimodal reasoning. However, prevailing reinforcement learning (RL) paradigms lack explicit counterfactual enhancement and causal learning mechanisms. This fundamental deficiency results in severe grounding failures,…

Learning Structurally Stabilized Representations for Lossless DNA Storage

AAAI 2026technical

This paper presents Reed-Solomon coded single-stranded representation learning (RSRL), a novel end-to-end model for learning representations for lossless DNA data storage. In contrast to existing learning-based methods, RSRL is inspired by both error-correction codec and structural biology. Specific

Personalized Federated Learning under Local Supervision

ICCV 2025poster

A crucial issue in federated learning is the heterogeneity of data across clients, which may lead to model divergence, eventually deteriorating the model performance. Personalized federated learning (pFL) has been shown to be an effective approach to addressing data heterogeneity in federated learni…

Voronoi-grid-based Pareto Front Learning and Its Application to Collaborative Federated Learning

ICML 2025poster

Multi-objective optimization (MOO) exists extensively in machine learning, and aims to find a set of Pareto-optimal solutions, called the Pareto front, e.g., it is fundamental for multiple avenues of research in federated learning (FL). Pareto-Front Learning (PFL) is a powerful method implemented us…

iDPA: Instance Decoupled Prompt Attention for Incremental Medical Object Detection

ICML 2025poster

Existing prompt-based approaches have demonstrated impressive performance in continual learning, leveraging pre-trained large-scale models for classification tasks; however, the tight coupling between foreground-background information and the coupled attention between prompts and image-text tokens p…

FedCompetitors: Harmonious Collaboration in Federated Learning with Competing Participants

AAAI 2024technical

Federated learning (FL) provides a privacy-preserving approach for collaborative training of machine learning models. Given the potential data heterogeneity, it is crucial to select appropriate collaborators for each FL participant (FL-PT) based on data complementarity. Recent studies have addressed…

Free-Rider and Conflict Aware Collaboration Formation for Cross-Silo Federated Learning

NeurIPS 2024poster

Federated learning (FL) is a machine learning paradigm that allows multiple FL participants (FL-PTs) to collaborate on training models without sharing private data. Due to data heterogeneity, negative transfer may occur in the FL training process. This necessitates FL-PT selection based on their dat…

Exploring Leximin Principle for Fair Core-Selecting Combinatorial Auctions: Payment Rule Design and Implementation

IJCAI 2023poster

Core-selecting combinatorial auctions (CAs) restrict the auction result in the core such that no coalitions could improve their utilities by engaging in collusion. The minimum-revenue-core (MRC) rule is a widely used core-selecting payment rule to maximize the total utilities of all bidders. However…
